[rabbitmq-discuss] RabbitMQ broker behind an ELB

[Dhinesh Kumar]

Hi Marek,

Later i found out that the Amazon ELB has a 60 seconds period of inactivity.
So the connection was getting closed after 60 seconds.
Setting the heartbeat in the connection factory helped in not losing the
connection.

Thanks,
Dhinesh Kumar
